Abstract: <P>PROBLEM TO BE SOLVED: To provide a rice cooker capable of improving the rice boiling capability without unevenness in the boiled-up rice and without requiring labors or a plurality of devices.  <P>SOLUTION: The rice cooker has a pressure increasing/reducing means 10 for compressing or decompressing the inside of a pot 1 in which an object to be cooked is stored, and processes for reducing and increasing the pressure inside the pot 1 are executed by the pressure increasing/reducing means 10 in a water immersing step for letting water absorbed in the object to be cooked in a boiling step. By executing the processes for reducing and increasing the pressure inside the pot 1 by the pressure increasing/reducing means 10 in the water immersing step in this way, water is absorbed in the rice to the core without requiring labors or a plurality of devices, and water can be absorbed and flavors can be added to the core of rice or foodstuff which can not easily absorb water in a relatively short period of time. In other words, the rice boiling capability can be improved without unevenness in the boiled-up rice.  <P>COPYRIGHT: (C)2008,JPO&INPIT
